Systems and methods for providing power to a multi-purpose transaction card

ABSTRACT

A controller of a transaction card may cause the transaction card to be in a first state. The transaction card may include a battery and at least one other component. In the first state, the battery does not provide power to the at least one other component of the transaction card. The transaction card may receive a signal from a near-field communication (NFC) device and may cause the transaction card to be in a second state based on receiving the signal. In the second state, the battery provides power to the at least one other component of the transaction card. The transaction card may perform a transaction based on the transaction card being in the second state.

RELATED APPLICATION

This application is a continuation of U.S. patent application Ser. No. 16/876,771, filed May 18, 2020 (now U.S. Pat. No. 11,068,882), which is incorporated herein by reference in its entirety.

BACKGROUND

A transaction card (e.g., a credit card, a debit card, a gift card, an automated teller machine (ATM) card, a rewards card or a client loyalty card, and/or the like) and/or a device (e.g., a smart transaction card, a smartphone, and/or the like) may be used in a transaction to pay for a product or service at a transaction terminal (e.g., point of sale (PoS) terminal) of an individual or a business engaged in the sale of goods or services. The transaction card may include an integrated circuit (IC) chip to improve security with respect to use of the transaction card.

SUMMARY

According to some implementations, a method may include causing, by a controller of a transaction card, the transaction card to be in a first state, wherein the transaction card includes a battery and at least one other component, and wherein the battery does not provide power to the at least one other component when the transaction card is in the first state; receiving, by the transaction card, a signal from a near-field communication (NFC) device; causing, by the controller, the transaction card to be in a second state based on receiving the signal, wherein the battery provides power to the at least one other component when the transaction card is in the second state; and performing, by the transaction card, a transaction based on the transaction card being in the second state.

According to some implementations, a transaction card may include one or more memories; and one or more processors, communicatively coupled to the one or more memories, configured to: receive, when the transaction card is in a first state, a first signal from a near-field communication device, wherein a power source of the transaction card does not supply power to a set of components of the transaction card when the transaction card is in the first state; cause the transaction card to be in a second state for a predetermined time period based on the first signal, wherein the power source provides power to the set of components when the transaction card is in the second state; and perform a transaction based on the transaction card being in the second state.

According to some implementations, a non-transitory computer-readable medium may store one or more instructions. The one or more instructions, when executed by one or more processors of a transaction card, may cause the one or more processors to: receive, when the transaction card is in a first state, a first signal from a near-field communication device, wherein the transaction card includes a power source and one or more other components, wherein the power source of the transaction card does not supply power to the one or more other components when the transaction card is in the first state; transmit a second signal to at least one of the power source or the one or more other components to cause the transaction card to be in a second state based on the first signal, wherein the power source provides power to the one or more other components when the transaction card is in the second state; and perform a transaction based on the transaction card being in the second state.

DETAILED DESCRIPTION

The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.

In some instances, a transaction card (e.g., a credit card, a debit card, a gift card, an automated teller machine (ATM) card, a rewards card or a client loyalty card, and/or the like) may include an electronic circuit with components that are powered by a power source internal to the transaction card (e.g., a battery and/or the like). For example, an internal power source may provide power to one or more communication interfaces, one or more processors, one or more user interfaces, one or more memories, one or more storage components, and/or the like of the transaction card.

The transaction card may include a secure element capable of securely hosting an application and/or an operating system, storing confidential data associated with the application and/or operating system, and/or storing cryptographic data (e.g., a cryptographic key and/or the like) associated with the application and/or operating system. For example, a secure element may host an application for performing a transaction and may store credentials and/or cryptographic keys for authenticating the transaction. A secure element may assist with performing different types of transactions, such as financial transactions (e.g., contactless transactions) using different payment methods, user identification, access, transit, ticketing, and/or the like. To perform different types of transactions, the transaction card may load different applications onto the secure element and may execute a particular application to perform a particular type of transaction.

The transaction card may use power obtained from the internal power source to load an application onto the secure element, unload an application from the secure element, configure an application for performing a transaction, and/or the like.

To conserve power, a transaction card having an internal power source may include a component for determining when the internal power source is to provide power to one or more components of the transaction card. For example, the transaction card may utilize an accelerometer to detect a movement of the transaction card. The internal power source may provide power to the transaction card based on a detection of the movement.

By utilizing a component to determine when the internal power source is to provide power to one or more components of the transaction card, an amount of power provided by the internal power source can be reduced relative to an amount of power provided by an internal power source that constantly provides power to the components of the transaction card. However, to enable the component to be able to determine when the internal power source is to provide power to the transaction card, the internal power source must constantly provide power to the component, thereby reducing the amount of power available to be provided to the components of the transaction card and/or reducing an amount of time before the internal power source is required to be recharged.

Some implementations described herein permit a transaction card to switch between an unpowered state and a powered state based on an NFC signal received from an NFC device. In this way, an internal power source may selectively provide power to the transaction card based on an event, without having to constantly provide power to a component used to determine when the internal power source is to provide power to other components of the transaction card. In this way, the amount of power available to be provided to the components of the transaction card and/or an amount of time before the internal power source is required to be recharged is increased.

By increasing the power available to be provided to the components of the transaction card and/or the amount of time before the internal power source is required to be recharged, an internal power source of a transaction card can maintain a charge between transactions at transaction terminals, and thus ensure that the transaction card has full functionality between the transactions at the transaction terminals. As such, communication resources, processing resources, and/or the like, that may otherwise be used to access or utilize a function of the transaction card can be conserved. For example, if a user device or a transaction terminal is to attempt to access a payment token from the transaction card, some implementations described herein can ensure that the transaction card has power to provide the payment token to the user device or the transaction terminal. In such a case, communication resources and/or processing resources of the user device and/or the transaction terminal can be conserved by ensuring that the transaction card has enough power to provide the payment token and avoiding loss of functionality due to a lack of charging the internal power source between transactions at transaction terminals.

FIGS. 1A-1G are diagrams of one or more example implementations 100 described herein. As shown in FIG. 1A, a multi-function transaction card that is capable of interacting with a transaction terminal to submit payments and/or interacting with a transaction card to receive payments.

As shown in FIG. 1A, the multi-function transaction card may include, among other components (e.g., as described elsewhere herein), a power source internal to the multi-function transaction card. The power source may be configured to selectively provide power to components of the multi-function transaction card based on an operating mode or state of the multi-function transaction card. In some implementations, the operating mode may be an unpowered mode and/or a powered mode of operation.

For example, as shown in FIG. 1A, and by reference number 102, the multi-function transaction card may operate in an unpowered mode. As shown by reference number 104, the power source may not provide power to the components of the multi-function transaction card based on the multi-function transaction card operating in the unpowered mode.

In some implementations, while operating in the unpowered mode, a user may desire to utilize the multi-function transaction card to conduct a transaction (e.g., to purchase of a good and/or service). As shown in FIG. 1B, and by reference number 106, to conduct the transaction, the user may cause the multi-function transaction card to be in proximity to (e.g., within about 4.0 cm) a near-field communication (NFC) field generator, such as, for example, a point of sale (PoS) transaction terminal, a mobile device, a smart phone, and/or the like.

In some implementations, the multi-function transaction card may transition from operating in the unpowered mode to the powered mode based on the multi-function transaction card receiving an NFC signal from the NFC field generator in connection with conducting a transaction. For example, as shown in FIG. 1C, and by reference number 108, the multi-function transaction card may receive a signal from the NFC field generator based on the multi-function transaction card being in proximity to the NFC field generator.

In some implementations, as shown in FIG. 1D, and by reference number 110, the multi-function transaction card may cause the multi-function transaction card to operate in the powered mode based on the signal received from the NFC field generator. For example, the multi-function transaction card may harvest energy from the NFC signal generated by the NFC field generator. The multi-function transaction card may use the harvested energy to transmit a signal (e.g., a hardware interrupt signal) to the power source to cause multi-function transaction card to operate in the powered mode. As shown in FIG. 1D, and by reference number 112, the power source may provide power to the components of the multi-function transaction card based on the multi-function transaction card operating in the powered mode.

In some implementations, the multi-function transaction card may operate in the powered mode based on data obtained by an accelerometer included in the multi-function transaction card. For example, a user may provide an input to the multi-function transaction card via an input component embedded in a card body of the multi-function transaction card, such as a button, a switch, a touch sensor, and/or the like. The multi-function transaction card may operate in a minimal power mode based on the input. The power source may provide power to the accelerometer based on the multi-function transaction card being in the minimal power mode. The accelerometer may utilize the power provided by the power source to obtain data indicating a movement of the multi-function transaction card. The multi-function transaction card may detect the movement based on the data and may begin operating in the powered mode based on detecting the movement.

In some implementations, the multi-function transaction card may use power provided by the power source conduct a transaction based on the multi-function transaction card operating in the powered mode. For example, as shown in FIG. 1E, and by reference number 114, the multi-function transaction card may use power obtained from the power source to provide card data to the NFC field generator.

In some implementations, the multi-function transaction card may use power provided by the power source to perform one or more operations associated with a transaction based on the multi-function transaction card being in the powered mode. For example, the multi-function transaction card may use power provided by the power source to monitor transaction data, to communicate between the controller and the secure element, to enhance a speed and/or range of the transaction, to perform fraud monitoring, to perform transaction analytics, to load an application associated with the transaction into a memory of the secure element, to unload an application not associated with the transaction from the memory of the secure element, to configure an application for performing the transaction, and/or another operation associated with a transaction.

Additionally, and/or alternatively, the multi-function transaction card may use power provided by the power source to perform one or more other types of operations based on the multi-function transaction card being in the powered mode. For example, the NFC field generator may be a user device (e.g., a mobile device, a computer, a laptop, a smart phone, and/or the like) and the user may bring the multi-function transaction card in proximity to the NFC field generator to initialize the multi-function transaction card, to transfer user data from the user device to the multi-function transaction card, to perform an update operation to update an application stored on a memory of the secure element, to transmit transaction data to the user device, to synchronize data between the multi-function transaction card and the user device, and/or another type of operation.

In some implementations, the multi-function transaction card may perform an operation for providing energy to the power source. For example, the power source may include a rechargeable battery. The multi-function transaction card may harvest energy from the signal transmitted by the NFC field generator and may use the harvested energy to recharge the rechargeable battery.

In some implementations, the multi-function transaction card may operate in the powered mode based on the one or more inputs. For example, a user may provide, to the multi-function transaction card (e.g., via one or more input components embedded in a card body of the multi-function transaction card, such as one or more buttons, switches, touch sensors, and/or the like), one or more inputs (e.g., information regarding a transaction) to initialize and/or enable the functionality of the multi-function transaction card. The multi-function transaction card may operate in the powered mode based on the one or more inputs.

In some implementations, as shown in FIG. 1F, and by reference number 116, the multi-function transaction card may stop operating in the powered mode and begin operating in the unpowered mode based on a set of conditions for operating in the unpowered mode being satisfied.

In some implementations, the set of conditions may include a condition associated with a completion of the transaction. For example, the NFC field generator may transmit a signal to the multi-function transaction card indicating that the transaction and/or the other operation has been successfully conducted. The multi-function transaction card may receive the signal (e.g., via the NFC antenna) and may determine to stop operating in the powered mode and to begin operating in the unpowered mode based on the signal indicating that the transaction has been successfully completed.

In some implementations, the set of conditions may include a condition related to an expiration of a time period. The time period may start at a time that the multi-function transaction card begins operating in the powered mode and may correspond to a predetermined period of time (e.g., 30 seconds, 1 minute, 2 minutes, and/or another period of time) for which the multi-function transaction card is to remain operating in the powered mode. For example, the multi-function transaction card may initialize a timer based on the multi-function transaction card operating in the powered mode. The multi-function transaction card may determine an expiration of the time period based on the timer (e.g., based on a value of the timer being equal to 0 and/or another value). The multi-function transaction card may stop operating in the powered mode and begin operating in the unpowered mode based on the expiration of the time period.

In some implementations, the multi-function transaction card may determine that the transaction and/or other operation is complete, and the multi-function transaction card may stop operating in the powered mode and begin operating in the unpowered mode prior to the expiration of the time period. For example, prior to the expiration of the time period, the NFC field generator may transmit a signal, to the multi-function transaction card, indicating that a transaction and/or an update operation is complete and/or that the multi-function transaction card is to begin operating in the unpowered mode. The multi-function transaction card may begin operating in the unpowered mode prior to the expiration of the time period based on the signal.

In other implementations, the multi-function transaction card may determine that the transaction and/or the other operation is not complete, and the multi-function transaction card may continue to operate in the powered mode after the expiration of the time period. For example, the multi-function transaction card may determine that the multi-function transaction card has not received a signal indicating that the transaction and/or the other operation is complete prior to the expiration of the time period. The multi-function transaction card may continue operating in the powered mode after the expiration of the time period based on the multi-function transaction card not receiving the signal prior to the expiration of the time period. The multi-function transaction card may subsequently receive a signal from the NFC field generator indicating that the transaction and/or the other operation is complete and may begin operating in the unpowered mode based on the signal.

In some implementations, the multi-function transaction card may continue operating in the unpowered mode after an expiration of a time period based on a signal received from the NFC field generator prior to the expiration of the time period. For example, the multi-function transaction card may perform an update operation with a user device to update an application stored in a memory of the multi-function transaction card. The user device may determine that the update operation will take longer than the time period and may transmit a first signal to the multi-function transaction card indicating that the multi-function transaction card is not to begin operating in the unpowered mode upon an expiration of the time period and/or that the multi-function transaction card is to continue operating in the powered mode until the multi-function transaction card receives a second signal from the user device indicating that the update operation is complete. The multi-function transaction card may continue operating in the powered mode after expiration of the time period based on the first signal. Subsequently, the multi-function transaction card may receive the second signal from the user device and may begin operating in the unpowered mode.

In some implementations, as shown in FIG. 1G, and by reference number 120, based on determining that the set of conditions are satisfied, the multi-function transaction card may operate in the unpowered mode. The power source may not provide power to the components of the multi-function transaction card based on the multi-function transaction card operating in the unpowered mode.

Some implementations described herein may allow the power source to provide power to the components of the multi-function transaction card for about 12-13 months before the power source needs to be recharged. In contrast, a multi-function transaction card utilizing a component that requires a constant supply of power to determine when to begin operating in a powered mode may be able to supply power to the components of the multi-function transaction card for about 2-3 weeks before the power source needs to be recharged. In this way, some implementations described herein may improve operation of the multi-function transaction card and conserve resources that would otherwise be wasted by a failed transaction (e.g., where the multi-function transaction card begins a transaction utilizing power supplied by the internal power source but runs out of power before the transaction is completed).

As indicated above, FIGS. 1A-1G are provided as one or more examples. Other examples may differ from what is described with regard to FIGS. 1A-1G.

FIG. 2 is a diagram of an example environment 200 in which systems, devices, and/or methods, described herein, may be implemented.

A chip reader of transaction terminal 220 may receive transaction card data from an IC chip (e.g., an EMV chip) of transaction card 210 and/or multi-function transaction card 260 when the chip is placed in contact with the chip reader. An RF signal reader of transaction terminal 220 may enable contactless transactions from transaction card 210 and/or multi-function transaction card 260 by obtaining transaction card data wirelessly from transaction card 210 and/or multi-function transaction card 260 as transaction card 210 and/or multi-function transaction card 260 comes within a range of transaction terminal 220 at which the RF signal reader may detect an RF signal from an RF antenna of transaction card 210 and/or multi-function transaction card 260.

In some aspects, multi-function transaction card 260 may include a single power source 268, which may supply power for performing a transaction and/or may supply power to one or more other components of multi-function transaction card 260 (e.g., a processor, a storage component, an input component, an output component, a communication interface, and/or the like). In some aspects, multi-function transaction card 260 may include multiple power sources 268. In some aspects, a single power source 268 may be dedicated to supplying power solely for performing a transaction, while other power sources 268 may supply power to other components of multi-function transaction card 260. In some implementations, multi-function transaction card 260 may include one or more solar cells and associated circuitry that enable various components of multi-function transaction card 260 to be powered by solar energy.

Additionally, or alternatively, power management component 270 may include a diode (e.g., an ideal diode) and/or a switch (e.g., a load switch) to control signals between power source 268 and secure element 274 (e.g., to couple or decouple power source 268 and secure element 274, to prevent signals from being passed between power source 268 and secure element 274, and/or the like).

Controller 272 includes one or more devices capable of receiving, generating, storing, processing, and/or providing information and/or instructions that assist with performing a transaction. For example, controller 272 may include a processor, such as processor 320 described below in connection with FIG. 3. Additionally, or alternatively, controller 272 may include memory, such as memory 330 described below in connection with FIG. 3. In some implementations, controller 272 may be directly, communicatively coupled to secure element 274 (e.g., via a dedicated, single-wire communication link).

Secure element 274 includes one or more devices capable of securely hosting an operating system and/or an application, and/or storing confidential information (e.g., a credential, cryptographic information, and/or the like).
